25Claims.

This invention relates to enamels and varnishes, and particularly to a finish that imitates the appearance of leather.

This application is a continuation in part of 5 application Serial No. 380,246, filed July 22, 1929,

now Patent 1,878,316.

It is the object of this invention to provide an enamel varnish which, when applied to a suitable surface, will give to it a finish imitating leather.

It is a further object of this invention to eliminate all blown oils and preoxidized oil thereby materially reducing the cost and improving the product.

The three essential features are:

The employment of a phenol formaldehyde synthetic resin.

The mixture of China wood oil and linseed oil and their preheating in order that the resulting product may be taken to the higher degree of heat of 480, with such retardation of the polymerization of the wood oil that is necessary.

The ultimate mixing of the resin (natural or synthetic) and the oils and the carrying of their 5 temperature above 450 degrees, that is from about 460 degrees F. to a point in the neighborhood of 480 degrees F. but not above.

It is an additional object to provide an enamel varnish which will employ in the formula cheaper gums and resins than heretofore have been possible in connection with varnishes of this of this invention type.

A typical formula is the following:

Pounds Amberol B/S 1 Lt. 6'1 Litharge 3 Manganese linoleate 8 (solid) Cobalt linoleate 2 (solid) 40 Gallons China wood oil 20 Linseed oil 2 Heavy petroleum naphtha 14 Light petroleum naphtha 14 Amberol is a phenol, formaldehyde, synthetic resin. It is made as follows:to one hundred parts of phenol aldehyde resin difflcultly fusible and only partly soluble in benzol and other sol- 50. vents and produced, for instance, by heating 108 parts of cresol with to '15 parts of formaldehyde (30% by weight) and distilling oi the water and the uncombined cresol, are added gradually to 800 parts of melted colophony. The whole 5 mixture is then heated in an autoclave until a "20 gallons of China wood resin is produced which is clear in the cold, homogeneous and free from smell of phenol. The volatile substances are then removed while stirring and 100 parts of glycerol of 28 'B. are added in small quantities whereupon the mixture 60 is heated to 250 C. and kept at this temperature for several hours while being stirred carefully.

A typical formula for amberol is shown in United States Patent No. 1,623,901.

In order to prepare this varnish, I first take oil or tung oil and 2% gallons refined linseed oil. These oils are mixed and heated at a normal rate to 480 F. They are then pulled from the fire. These oils may undergo an automatic rise in temperature. thereafter beyond 480 F., but this is unnecessary and too great a rise should be avoided.

When the temperature of these oils has started to drop reaching approximately 475 F., I add 3 pounds of litharge stirring until the litharge is taken up by the oil. The temperature of this batch is then run back and forth between 460 and 470 being held within this range for approximately 30 minutes and in some cases a little longer until sufficient body has been imparted to the oil and litharge.

. Thereafter I add 8 /2 pounds of manganese solid linoleate and 2 pounds of cobalt solid linoleate. These soluble driers melt into the batch.

I then add 6'7 pounds of synthetic resin solid, known to the trade as Amberol 13/8 1 Light. This is melted at a low heat. Then the temperature is carried back to approximately 425 F.

I then thin the batch at once with 14 gallons each of heavy and light petroleum naphtha. The resulting compound may be used by itself or in combination with the product of the formula hereinafter recited. If used with the next formula, they can be mixed together in proportion as high as one part each.

This formula is as follows:

Pounds South sea g 67 Litharge Manganese linoleate 8% Cobalt lin 2 Gallons China wood oil 20 Linseed oil 2 Heavy petroleum naphtha 20 Light petroleum naphtha 20 The cooking is carried out in this manner. Sixty-seven pounds of South Sea gum, also known as Batu gum, are run in the ordinary approved 1 0 fashion customary in varnish'making. Then 20 gallons of China wood on and 2% gallons of refined linseed oil are mixed and heated slowly until they reach 300 or 350 F., then they are added 5 slowly to the gum when the latter has been well run.

The mixture is then carried to a temperature of 460 to 470 F. and held within this range in order to impart body to the mixture for about 30 minutes or a little longer.

. I then stir into the batch 3 /2 pounds of litharge until it is taken up and fully incorporated in the batch. The 8 2 pounds of manganese solid linoleate and 2 pounds of cobalt solid linoleate are allowed to melt in the batch.

I then thin at once with 20' gallons each of heavy and light petroleum naphtha.

Turpentine may be substituted for the naphtha. Either the natural gum or a synthetic product as Amberol may be employed. When the natural product is used the result is a liquid of greater viscosity. I 1

The fundamentalbasis is the combination of a gum and a low cooked China wood oil. The litharge has the function of drying the compound through and through while the manganese and cobalt linoleates act primarily as surface or finish driers. The naphthas act as thinners. The linseed oil is an antipolymerizing agent.

Be it understood that the result of my'invention is applied to any suitable surface and baked in the usual manner which brings about the appearane of leather on the surface so treated with my product. i

It will be understood that I desire to comprehend within. my invention and within the scope of my claims such modifications as may be fairly comprehended within such claims and invention due to necessary modifications to adapt my invention to varying conditions of supply and of use and to varying purposes.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:
